iPhone freezing, screen flickering

Go to settings-general-about-diags&usage to see any relevant crash reports. Restore to the newest OS to see if the issue persists. If the phone still freezes, it is usually a hardware issue. You may have to replace components or even the logic board

Hi, my iPhone 4S is having similar problems but it flickers very badly. It's the worst on the camera or on snap chat anything that has anything to do with a camera. But no problem whilst using the front camera. Any suggestions on what it may be, or what is causing it, also my lock button ribbon cable was taken out because it was making my phone freeze and crash ever 5 minutes, also I have iOS7.2 if that helps. Thanks

Cleaning the cache should resolve the freezing problem. As to flicking, try to replace the screen protector instead. It seems it was dirty.

reboot it 2 times

than reset it

This worked for me!

Hey I don't know if this will help but I heared if u go to settings and turn off auto brightness the. Turn it down leave it for 5 minuets and then turn auto brightness back on and then turn the brightness back up and it may work but it might not worth a try though

1: Turn Down Brightness

2:Wait 5 min. To 2 hr

IT WILL WORK
